giúp với
và ai giải được gọi cụ
Các phân số 1/3: 1/6: 5/2: 3/2 xếp theo thứ tự tăng dần
a. 1/3; 1/6; 5/2; 3/2 b. 1/3; 5/2; 1/6; 3/2 c. 1/6; 1/3; 3/2; 5/2 d. 1/6; 3/2; 3/2; 5/2
a. 2/5 ; 3/7 * 3/7 ; 2/5 + 1999 =
b, 1/2 * 2/3 : 5/6 * 5/6=
c, 2/3 ; 4/5 ; 5/6 ; 8/7=
dãy phân số đc sắp xếp theo thứ tự từ lớn đến bé là :
a :2 / 3 ; 5 / 6 ; 4 / 2
b : 5 / 6 ; 2 / 3 ; 4 / 2
c : 4 / 2 ; 5 / 6 ; 2 / 3
d : 4 / 2 ; 2 / 3 ; 5 / 6
a) 60 × (7/12 + 4/15) =
b) 5/6 ×( 6/5 - 6/7 ) =
c) 1/2 × 2/3 × 3/4 × 4/5 × 5/6× 6/7 × 7/8 × 8/9 =
Tìm x biết :
x + 4/5 = 4/5 + ( 3/7 + 3/5 ) 5/7 + x/35 = 4/5
x < 3/4 + 2 2/3 + 1 < x < 5/6 + 4
x< 5/6 - 3/4 2/3 < x < 2 - 5/6
Các phân số được sắp xếp theo thứ tự từ lớn đến bé là:
A. 2/3; 5/6; 4/2 B.5/6; 2/3; 4/2 C.4/2; 5/6; 2/3 D.2/3; 4/2; 5/6
Các bạn giúp mình nhé
